Slow neutrons are used in a very broad spectrum of scientific investigations. I will discuss how neutrons are liberated from nuclei and lowered in energy to regimes of interest. I will also discuss some examples of experiments, mainly motivated by questions in nuclear/particle/astrophysics.

Evidence is presented for the finite wave vector crossing of the two lowest one-dimensional spin-split subbands in quantum point contacts fabricated from two-dimensional hole gases with strong spin-orbit interaction. This phenomenon offers an elegant explanation for the anomalous sign of the spin polarization filtered by a point contact, as observed in magnetic focusing experiments. Anticrossing is introduced by a magnetic field parallel to the channel or an asymmetric potential transverse to it.
It’s often useful to have a private conversation within a public world. What role can quantum cryptography play in keeping conversations private? Sometimes described as providing “unconditional security guaranteed by the laws of quantum physics,” its security implications are both tantalizing and surprisingly elusive. This talk introduces quantum cryptography and describes the speaker’s experience creating several types of quantum cryptography equipment, within the broader context of mainstream cryptography and secure communications.
